3.60

What the judge sees: Original (Chinese) 这是一幅扁平风格的卡通插画:一只白色的鸟站在一辆深蓝色线条构成的自行车上,鸟有灰色的翅膀、头顶几簇羽冠、一只黑色圆眼和一个很长的橙色喙,两条细腿踩在车架附近。自行车有两个浅蓝色填充、深蓝色边框的圆形车轮,车架由几条直线组成的三角形构成,两个车轮外侧各有一道橙色弧线。背景是浅蓝色的天空,右上角有一个黄色圆形太阳,被鸟喙部分遮挡,画面底部是一片起伏的绿色草地。

The front wheel floats on its own, there's no handlebars or saddle, and the bird just hangs above the frame, so it doesn't count as riding.
